Abstract

This response to papers by Leah Ceccarelli, Randy Harris, and Carl Herndl and Lauren Cutlip in the “Horizons of Possibility” panel at the 2012 ARST Vicentennial conference raises questions about each of the visions as they relate, respectively, to ARST audiences, brain science, and sustainable planets and programs. It also suggests renewed attention to communication technologies by scholars studying the rhetoric of science and technology, maintaining that rhetoricians need to come to terms with emerging twenty-first century communicative forms.
